Sheets

Basic client for reading and writing to Google Sheets from desktop applications

Examples

You need to create a project and credentials via these instructions:

• https://developers.google.com/workspace/guides/create-project
• https://developers.google.com/workspace/guides/create-credentials

import { SheetsClient } from "@altangent/lib-sheets";

// obtained from google
const credentials = {};
const scopes = ["https://www.googleapis.com/auth/spreadsheets"];

// construct a client
const client = new SheetsClient(credentials, scopes);

// obtain the code request URL
console.log(client.requestCodeUrl());

You can then navigate to the generated URL and grant access which will generate a code. This that is used to obtain a token.

const code = "<OBTAINED FROM GOOGLE>";

// request the token
client.requestToken(code).then(console.log).catch(console.error);

You can now use the token in subsequent requests.

const client = new SheetsClient(credentials, scopes, token);

// query a range
client
    .getRange("11111111111111111111111111111111111111111111", "Sheet1!A2:F")
    .then(console.log)
    .catch(console.error);

// update a range
client
    .setRange("11111111111111111111111111111111111111111111", "Sheet1!N50:P51", [
        ["1", "2", "3"],
        ["4", "5", "6"],
    ])
    .then(console.log)
    .catch(console.error);
